The Valley is particularly vulnerable to air pollution formation because of its topography, climate, and growing population. Surrounding mountains trap just about anything near the Valley floor where people live and breathe. The Valleys increasing population growth has caused the San Joaquin Valley to rank with Los Angeles and Houston in most measures of air pollution. In addition, the Valley’s hot, summer temperatures, transform car exhaust, manure gases and other emissions into a smoggy
Each event normally lasts 9-12 months they often starts in spring reaches its strongest point between December and January and appears to end around may of the next year. It frequently brings record rainfall to Peru, Chile and Ecuador. Southern Australia is often hit by drought and it also sees an increase in its temperatures. South east Australia heats up and because it is already dry due to drought there is a massive increase in the chance of bush fires. The other effects on Southern Australia are; lower rainfall, fewer cyclones, late and weak tropical monsoon and lower
Another physical factor is whether the country has space which stores extra water such as aquifer, as this can be something for a country to use if the main water supply does potentially run out. For example Mexico has a low amount of water stress due to having a large aquifer underground, where as Saudi Arabia has a high water stress level because it has no alternative water supply. Climate change is large physical factor which contributes to the pattern of water stress as it can cause climates to become extreme. For example, in Indonesia climate change has increased the amount of
Within the Loop Current there is warm water that extends fairly deeper than the water surrounding it. Hurricanes usually churn up slightly cooler water allowing for some weakening of the storm; however a hurricane moving over the Loop Current churns up warmer water that extends deeper into the ocean. Camille's extraordinary strength could be blamed in part due to the assumption that it tracked directly up the axis of the Loop Current. After landfall, Camille dropped torrential rains on the southern states with anywhere from 2 to 11 inches of rain. Camille eventually strengthened somewhat as it moved more inland bringing major destruction to the state of Virginia with damage to property and life.
Global warming will only cause an increase in these issues along with additional problems that could eventually end this civilization, if we don’t work hard on improving our efforts on managing all the different types of pollution and waste that contributes to this major concern. 2. Water Issues, was an extremely important area of local environmental concern this summer. 70% of our planet’s surface is water, but most of that is salt water. Freshwater though essential to life, is one of the rarest and most endangered resources on our progressively fragile planet.
The differences in urban climates are due to several reasons. Urban heat island affect is known to heat urban areas, urban areas are generally much hotter than surrounding rural areas. As you move from city centres into nearby rural areas the temperature is known to drop by up to 10 degrees. Around half of the world’s population live in urban areas but this rate is expected to increase to 70% by 2030. Negative affects relating to urbanisation is becoming increasingly concerning especially as there is an increased number of people who are moving out of the rural area into the urban/suburban areas.
In the summer the city can be up to 5°C warmer than surrounding rural areas. This could prove to have disastrous effects on the city and its people. Many people could get heat stroke, or dehydration and cause a strain on the emergency services, further it may cause deaths in the very young and old age categories. Urban areas use building materials such as concrete, tarmac and bricks. Theses surfaces have a higher thermal capacity than natural surfaces and are able to absorb large quantities of heat during the day and slowly release it during the night.
Secondary effects include respiration problems from the plumes of smoke, land slides from soil erosion, and economic losses. As the fires burn large plumes of smoke begin to saturate the air and make the quality of air very poor for breathing. According to (usgs.gov) over 70% of people were affected by respiratory problems from poor air quality in and around the San Diego area during the 2007 wildfires. Another secondary impact of wildfires is soil erosion. Soil erosion occurs when the land is depleted of valuable nutrients making it susceptible to landslides and mudslides in the wet
The inability of rain will led to increase heat and that may lead to have dryer soils and that would have a big impact in our agriculture. Productivity will decline. Even though if that happens irrigation to fill water needs could be a way to help the need of rain. The soil of Indiana is a major natural resource that temperature changes will affect, hotter drier summers, would be the main cause of loss soil organic matter and will result an increased soil respiration. Loss of soil will decrease the ability to retain moisture and specially essential nutrients for plant growth.
The Sierra Nevada create uplift of moist oceanic air masses and it rains. Much of the water reaches the San Joaquin valley but by the time the storms reach the eastern Sierra and Owens Valley, most of the water has been wrung from the clouds. The White and Inyo mountains, only twenty five miles east of the Sierra crest, are semi-arid. They suck the remaining water from the skies and by the time the air reaches the Saline and Death Valleys, it is bone dry. Such weather patterns have a great influence on the surface geology as well: erosion, deposition and chemical alternation take place rapidly in many parts of
